Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458366, here are decompositions:

67 + 31458299 = 31458366
89 + 31458277 = 31458366
127 + 31458239 = 31458366
179 + 31458187 = 31458366
193 + 31458173 = 31458366
197 + 31458169 = 31458366
283 + 31458083 = 31458366
353 + 31458013 = 31458366

Showing the first eight; more decompositions exist.
